canonical but for one loader only? That's not really what I'm looking for.

I really like the output of 
pbl --default-settings
Any chance this will work with systemd-boot?
On a systemd-boot system it prints: Option --default-settings not available for
systemd-boot.

I would really like to have a truly universal way to give me a reasonable
default kernel without caring which boot loader is being used. Until now this
has been /boot/vmlinuz. Is there future in pbl, or something similar that would
provide this information?
